why are objects that fall near earth’s surface rarely in free fall?

a. gravity does not act on objects near earth’s surface.

b. air exerts forces on falling objects near earth’s surface.

c. the objects do not reach terminal velocity.

d. the objects can be pushed upward by gravity.

If a reaction has g of -136kj at 110°c, will it be spontaneous at this temperature (110°c)? yes or no

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

If you used the method of initial rates to obtain the order for no2, predict what reaction rates you would measure in the beginning of the reaction for initial concentrations of 0.200 m, 0.100 m, & 0.050 m no2.
